Yes, that's how proportion works; if thighs like food take a smaller portion of spending, some other things will take a bigger share.
GP comment is cited food as the first item; and decades (not 5 year) as the reference timeframe, so I focused on that. I am sure that by cherry picking both items and timeframe (look at food but only over 5 year; education but only since the 60's; telecommunication but only since the price hike of last week) you can paint a different story, but that's not the point here.
At least for eduction this increase can be explained by the simple supply and demand; Americans on average have never been as educated as today. The demand for college degrees and above has skyrocketed; according to the same source as you use [1]. Stuff costs less, so more people put their children through college, so education price goes up; it's the symptom of a good thing.
